Hi,
I am on CentOS 6.2 (kernel-2.6.32-220.el6.x86_64.rpm,
lvm2-2.02.87-6.el6.x86_64.rpm). I am seeing an issue similar to
https://bugzilla.redhat.com/show_bug.cgi?id=651007 where I still have
snapshot lvs present after I merge them back into the origin devices.
The steps are :
- create snapshot
- lvconvert --merge (on open lv so that the merge will happen on next reboot)
- reboot
- after reboot the lvs have been restored to original, but 'lvs -a'
still shows snapshot lvs
I was seeing many I/O errors during bootup like are shown in comment
13 of https://bugzilla.redhat.com/show_bug.cgi?id=651402 . I disabled
dmraid on bootup and I no longer get these errors but the snapshot lvs
are still present after the merge has taken place.
lvchange --refresh will clear up the snapshot lvs.
I do notice that dracut is touching the lvs (the ones to be merged)
early in the boot process:

Welcome to CentOS
Is there an issue with dracut accessing and mounting the root lv
(which was set to be merged on next activation) ?
Note: dracut version is dracut-004-256.el6.noarch.rpm
Thanks for any help!
